The Lowdown
Alright, folks, Rusty here. Let’s be straight with you. This 16-day window is a tough one. We’ve got no proper surf on offer for the foreseeable future, and I mean none. The good news is that this kind of blank run isn't exactly normal for this stretch of coast, so I wouldn't go selling the boards just yet. Forecasts can flip, and when they do, it usually doesn't stay flat for long.
Right now, through the end of August and into the first week of September, it’s all cross-shore wind and lumpy, weak waves. We’re talking about chest-high slop at best, with a lot of poor surf conditions and low energy. The water temp at Kohala Lighthouse is sitting at 82°F, which is about average for this time of year, so at least it’ll be warm while we’re all getting frustrated.
The only real pulse of energy shows up on September 4th. That’s a week and a half out, so treat it with some caution, but the numbers are interesting. There’s a solid groundswell forecast with a period pushing 13 seconds and the energy jumping way up there (1732). The problem is, the wind is still going to be howling onshore-ish, which is a bummer. The swell is hitting 8ft, so it’s not for the faint of heart, and unless that wind clock around, it’s going to be a mess. Still, it’s the only standout on the board, promising but far from a sure thing.
After that, the swell fades back down, and we’re back to the same story: cross-chop and weak energy. The very tail end of the window shows a little more life around September 8th, with 8ft swells, but the period drops back down to 7 seconds, which makes it a bit of a mushburger. For the advanced crew, it might be worth a paddle, but for everyone else, it’s a hard pass.
Honestly, this setup, with the significant swell and the strong cross-shore winds we’re seeing, is looking a lot more interesting for the kite surfers than for us paddle surfers. Keep the wetsuit on, wait for that 4th to roll around, and cross your fingers for a wind shift.
This is Rusty, signing off.
